I think there should be more of that limit, gherns get nice flavor from that mechanic, but i think some of them could get limit of 2 for sake of balance
x2 makes for less diversity, as for balance that's another issue. There are currently plenty of Ghern units to choose from with Overseer Moga, equips like Ghern Helm and the relic Ghern Scarecrow, without including Cultural Contamination to keep your moga buffed...
Ya I dont really have any issue with it more just wanted to see what everyones thoughts on it would be
